INTRODUCTION
Welcome to the AR-B1631ET Single Board Computer, the AR-B1631ET low power AMD Geode
LX800 processor board with the advanced chipset CS5536 (CS5535). The board is designed for
extreme environments, it can be operated from -40°C to +75°C which can make a lot of outdoor
applications available, such as Traffic Control, Vehicle Computer, Remote Workstation, Outdoor
Data Acquisition, Aviation or Military industries.
ACROSSER’s Extended Temperature Products contain onboard components that have been
chosen to withstand extreme operating temperatures. This platform has been fully loaded and
passed robust thermal cycling tests. It is a reliable, long life time and cost effective Extended
Temperature solution for your application.
In addition, the AR-B1631ET provides on chip VGA. The VGA, which provides up to
1920x1440x32bpp at 85Hz and 1600x1200x32bpp at 100HZ resolutions. The VGA memory is
shared with the main memory (2M, 4M, or 8M). AR-B1631ET also has 18-bit LVDS function in
the system, with a resolution up to 1600x1200x32bpp at 60Hz.
The AR-B1631ET is loaded with special on-board features that rival full-size systems. It has one
network controller on board, uses Realtek RTL8100BL LAN controller, a fully integrated
10/100BASE-TX solution with high performance networking functions. Supports Compact
Flash™ Type I interface. Plus optional support for AC97 sound with CD-input. The AR-B1631ET
also includes one 200-pin SO-DIMM DDR sockets for up to 1GB total on-board memory. The
AR-B1631ET has four on-board serial ports; COM1 with RS232C, COM2, COM3 and COM4
with RS232C, 4 USB ports, and tough industrial grade construction. All these features make the
AR-B1631ET a very "system integrator friendly" solution, perfect for handling applications in the
harshest unmanned environments.

2.2 SYSTEM SETTINGS
Jumper pins allow you to set specific system parameters. Set them by changing the pin location
of the jumper blocks. (A jumper block is a small plastic-encased conductor that slips over the
pins.) To change a jumper setting, remove the jumper from its current location with your fingers
or small needle-nosed pliers. Place the jumper over the two pins designated for the desired
setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.
We will show the locations of the AR-B1631ET jumper pins, and the factory-default settings.
CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a
grounded wrist strap or touch an exposed metal part of the system unit chassis. The static
discharges from your fingers can permanently damage electronic components.

For using both Hard Disk and Compact Flash, you have to use the ATA33 IDE cable.
IF you want to use the ATA66/100 mode with the Hard Disk, you must put the jumper on
JP6 and use the special IDE cable.
The cable is like below：
NOTE 2:
USB connectors (USB1 & USB2) and USB Pin headers cannot be used together. If you
want to use USB connectors, you must take the USB cable on Pin Header.

BIOS CONSOLE
This chapter describes the AR-B1631ET BIOS menu displays and explains how to perform
common tasks needed to get up and running, and presents detailed explanations of the
elements found in each of the BIOS menus. The following topics are covered:
BIOS Setup Overview
Advanced CMOS Setup
Peripheral Setup
Boot
BIOS Exit
4.1 BIOS SETUP OVERVIEW
The BIOS is a program used to initialize and set up the I/O system of the computer, which
includes the ISA bus and connected devices such as the video display, floppy drive, and the
keyboard.
The BIOS provides a menu-based interface to the console subsystem. The console subsystem
contains special software, called firmware that interacts directly with the hardware components
and facilitates interaction between the system hardware and the operating system.
The BIOS default values ensure that the system will function at its normal capability. In the worst
situation the user may have corrupted the original settings set by the manufacturer.
After the computer is turned on, the BIOS will perform diagnostics on the system and display the
size of the memory that is being tested. Press the [Del] key to enter the BIOS Setup program,
and the main menu will show on the screen.
The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight
the option that you wish to modify, and then press the [Enter] key to select the option and to
configure the functions.
Setup Main Menu
16/30
The <Main> option allows you to view some basic system hardware configuration and to set the
system clock as well as error handling. If the CPU board is already installed in a working system,
you do not need to select this option anymore.
AR-B1631ET User’s Guide
Date & Time Setup
Highlight the <Date> field and then press the [Page Up] / [Page Down] or [+]/[-] keys to set the
current date. Follow the month, day and year format.
Highlight the <Time> field and then press the [Page Up] / [Page Down] or [+]/[-] keys to set the
current date. Follow the hour, minute and second format.
Hard Disk Setup
The BIOS supports 2 types of user settings. The BIOS supports <Pri Master> and <Pri Slave>,
<Sec Master> and <Sec Slave> so the user can install up to two hard disks.
4.2 ADVANCED
Standard CMOS Setup
Quick Power On Self Test
Allows the system to skip certain tests while booting. This will decrease the time needed to boot
the system.

PnP/PCI
Reset Configuration Data [Disable]
Normally, you leave this field Disabled. Select Enabled to reset the Extended System
Configuration Data (ESCD) when you exit the Setup if you have installed a new add-on and the
system reconfiguration has caused such a serious conflict that the operating system cannot
boot.
Resources Controlled By [Auto (ESCD)]
This field sets control over the IRQ resources by the automatic (ESCD) system or manual
assignment of IRQ channels. The default enables the automatic (ESCD) control. Configuration
options: [Auto (ESCD)] [Manual].

AR-B1631ET User’s Guide
Onboard Serial Port 1 [3F8/IRQ4]
Choose the serial port 1 I/O address. Do not set port 1, 2, 3 and 4 to the same address except
for Disabled or Auto.
Onboard Serial Port 2 [2F8/IRQ3]
Choose the serial port 2 I/O address. Do not set port 1, 2, 3 and 4 to the same address except
for Disabled or Auto.
Onboard Serial Port 3 [3E8/IRQ11]
Choose the serial port 3 I/O address. Do not set port 1, 2, 3 and 4 to the same address except
for Disabled or Auto.
Onboard Serial Port 4 [2E8/IRQ10]
Choose the serial port 4 I/O address. Do not set port 1, 2, 3 and 4 to the same address except
for Disabled or Auto.
Onboard Parallel Port [378H/IRQ7]
This field allows you to set the address of the onboard parallel port connector. If you disable this
field, the Parallel Port Mode and ECP DMA Select configurations are not available.
Configuration options: [Disabled] [378H/IRQ7] [278H/IRQ5]
Parallel Port Mode [SPP]
This field allows you to set the operation mode of the parallel port. [Normal] allows normal-speed
operation but in one direction only; [EPP] allows bidirectional parallel port operation; [ECP]
allows the parallel port to operate in bidirectional DMA mode; [ECP+EPP] allows normal speed
operation in a two-way mode. Configuration options: [Normal] [EPP] [ECP] [ECP+EPP]
Parallel port EPP Type [EPP1.7]
The mode depends on your external device that connects to this port.
ECP Mode use DMA [3]
This field allows you to configure the parallel port DMA channel for the selected ECP mode. This
selection is available only if you select [ECP] or [ECP+EPP] in Parallel Port Mode above.
Configuration options: [1] [3]
Onboard Audio [Enabled]
Should be enabled for active AC97
USB1 Controller [Enabled]
This should be enabled if your system has a USB Controller installed on the system board and
you want to use it. Even when so equipped, if you add a higher performance controller, you will
need to disable this feature.
USB2 Controller [Enabled]
This should be enabled if your system has a USB Controller installed on the system board and
you want to use it. Even when so equipped, if you add a higher performance controller, you will
need to disable this feature.
